ALGO :
 this script use an $op to know what to do.
 if $op is empty or none of the above values,
    - the default screen is build (with all records, or filtered datas).
    - the   user can clic on add, modify or delete record.
 if $op=add_form
    - if primkey exists, this is a modification,so we read the $primkey record
    - builds the add/modify form
 if $op=add_validate
    - the user has just send datas, so we create/modify the record
 if $op=delete_form
    - we show the record having primkey=$primkey and ask for deletion validation form
 if $op=delete_confirm
    - we delete the record having primkey=$primkey
